The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0034] Example 1

[0035] Combination Figures 1 to 8 As shown, the shell quick-release structure of the utility model is schematically shown, including a locking mechanism 30, a first mounting seat 10 and a second mounting seat 20. The first mounting seat 10 is provided with a locking hole 11, and the locking hole 11 is preferably a through hole.

[0036] like Figures 2 to 4 The locking mechanism 30 includes a locking pin 31 and a guide component 32. The locking pin 31 is slidably connected to the second mounting seat 20. The locking pin 31 can slide relative to the second mounting seat 20 along its axial direction, and the locking pin 31 can also rotate relative to the second mounting seat 20. The guide component 32 is arranged on the second mounting seat 20. The locking pin 31 is provided with a guide block 311. The guide block 311 is movably connected to the guide component 32, that is, the guide block 311 can move along the guide component 32, and the extension track of the guide component 32 is curved.

[0037] When the locking pin 31 rotates relative to the second mounting seat 20, the guide block 311 slides along the guide member 32 and causes the locking pin 31 to slide relative to the second mounting seat 20 along its axial direction, and the locking pin 31 penetrates or disengages from the locking hole 11. For example, when the locking pin 31 rotates forward relative to the second mounting seat 20, the guide block 311 slides along the guide member 32, and the guide block 311 drives the locking pin 31 to slide relative to the second mounting seat 20, so that the locking pin 31 penetrates into the locking hole 11, thereby connecting the first mounting seat 10 and the second mounting seat 20. When the locking pin 31 rotates reversely relative to the second mounting seat 20, the guide block 311 slides along the guide member 32, and the guide block 311 drives the locking pin 31 to slide relative to the second mounting seat 20, so that the locking pin 31 disengages from the locking hole 11, and the first mounting seat 10 and the second mounting seat 20 are separated from each other, thereby realizing the quick release of the first mounting seat 10 and the second mounting seat 20.

[0038] Specifically, a cylindrical sleeve 21 is provided on the second mounting seat 20. The sleeve 21 is hollow and its two ends are connected. The locking pin 31 can be slidably inserted into the sleeve 21. The guide component 32 is provided on the sleeve 21. The end of the locking pin 31 can extend out of the sleeve 21 or retract into the sleeve 21 under the drive of the guide component 32 and the guide block 311. In other words, when the locking pin 31 rotates forward relative to the sleeve 21, the guide component 32 and the guide block 311 drive the locking pin 31 to slide relative to the sleeve 21 along the axial direction of the locking pin 31, so that the locking pin 31 penetrates the locking hole 11; when the locking pin 31 rotates reversely relative to the sleeve 21, the guide component 32 and the guide block 311 drive the locking pin 31 to slide relative to the sleeve 21 along the axial direction of the locking pin 31, so that the locking pin 31 disengages from the locking hole 11.

[0039] Among them, combined Figure 4As shown, the guide component 32 is a guide groove opened on the side wall of the sleeve 21, and the extension trajectory of the guide groove is a curve. One end of the guide groove faces one end of the sleeve 21, and the other end of the guide groove faces the other end of the sleeve 21, which makes the projection of the guide groove on the axial section of the sleeve 21 L-shaped. The end of the guide block 311 can be slidably inserted into the guide groove, and the guide block 311 can slide in the guide groove. For example, when the locking pin 31 rotates relative to the sleeve 21, the guide block 311 slides from one end of the guide groove to the other end to drive the locking pin 31 to slide relative to the sleeve 21 along its axial direction.

[0040] like Figure 5 and Figure 6 In order to facilitate the reset of the locking pin 31, the locking mechanism 30 includes an elastic member 33, the two ends of which are respectively connected to the locking pin 31 and the sleeve 21. The locking pin 31 is driven by the guide member 32 and the guide block 311 to penetrate into the locking hole 11. At this time, the elastic member 33 is compressed, and the locking pin 31 can be separated from the locking hole 11 under the elastic force of the elastic member 33. Further, the inner wall surface of the end of the sleeve 21 is provided with a first blocking member 211, the first blocking member 211 is annular, and a mounting hole is provided in the middle of the first blocking member 211. The locking pin 31 is penetrated through the mounting hole. The outer wall surface of the locking pin 31 is provided with a second blocking member 312, which is preferably annular. The second blocking member 312 is arranged around the outer wall surface of the locking pin 31, one end of the elastic member 33 abuts against the end surface of the first blocking member 211, and the other end of the elastic member 33 abuts against the end surface of the second blocking member 312.

[0041] Combination Figure 3 As shown, in order to realize the detachable connection between the locking pin 31 and the first mounting seat 10, the locking mechanism 30 includes a rotation limit block 34, and the rotation limit block 34 is provided at the end of the locking pin 31, and a first rotation limit plane 341 is provided on one side of the rotation limit block 34, and the first mounting seat 10 is provided with a rotation limit groove 12, and a second rotation limit plane 121 is provided on the inner wall surface of the rotation limit groove 12, and the rotation limit block 34 is detachably connected to the rotation limit groove 12, and the first rotation limit plane 341 and the second rotation limit plane 121 are in contact with each other, so the rotation limit block 34 and the rotation limit groove 12 cannot rotate relative to each other, and because the cross-section of the rotation limit groove 12 is U-shaped, that is, an opening is provided on one side of the rotation limit groove 12, the rotation limit block 34 can be embedded in or detached from the rotation limit groove 12 through the opening, so as to realize the detachable connection between the locking pin 31 and the first mounting seat 10.

[0042] Preferably, a supporting groove 13 is provided on the first mounting seat 10 , the cross section of the supporting groove 13 is U-shaped, and the sleeve 21 is rotatably embedded in the supporting groove 13 .

[0043] Example 2

[0044] The difference between this embodiment and the first embodiment is that there are multiple locking holes 11 and locking mechanisms 30, and each locking hole 11 corresponds to a locking mechanism 30. At least two locking pins 31 are arranged opposite to each other, and the locking pins 31 are defined to have a locked state and an unlocked state. When the locking pins 31 are in the locked state, the locking pins 31 penetrate the locking holes 11, and when the locking pins 31 are in the unlocked state, the locking pins 31 are separated from the locking holes 11. The two locking pins 31 arranged opposite to each other move opposite to each other during the process of switching from the unlocked state to the locked state.

[0045] In this embodiment, the number of the locking pins 31 is two.

[0046] Example 3

[0047] In order to solve the same technical problem, this embodiment discloses a lamp, including an upper shell, a lower shell and the shell quick-release structure as described above, wherein the first mounting seat 10 is fixedly disposed on the upper shell, and the second mounting seat 20 is fixedly disposed on the lower shell.

[0048] To sum up, the first mounting seat 10 is provided with a locking hole 11, and the second mounting seat 20 is provided with a guide component 32. When the locking pin 31 rotates relative to the second mounting seat 20, the locking pin 31 is driven by the guide component 32 and the guide block 311 to penetrate into or disengage from the locking hole 11. When the locking pin 31 penetrates into the locking hole 11, the first mounting seat 10 and the second mounting seat 20 are rotationally connected around the axis of the locking pin 31. When the locking pin 31 disengages from the locking hole 11, the first mounting seat 10 and the second mounting seat 20 can be separated from each other to achieve quick release of the two.

[0049] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
